May is due to face her MPs at a meeting of the backbench 1922 committee on Wednesday.

One Conservative MP told the Mail on Sunday the prime minister should “bring her own noose” to the “show trial” - such was the anger at her leadership.

Backbencher Johnny Mercer last week described May’s government as a “shitshow”.

But he hit out at how some of his colleagues had chosen to make their criticisms.

“I would never use the language of some MP’s against the PM today, and condemn it utterly,” he tweeted.

Brexit minister Suella Braverman today refused three times to say whether she would support May if a no confidence vote was triggered.

Asked by Sky News if she would condemn the “brutal” language used about the prime minister, Braverman declined.

“Colleagues are free to express themselves in the way they wish,” she said.

Scottish First Minster Nicola Sturgeon also told Tory MPs to “get a grip”.

This morning I’ve seen quotes from Tories to the effect that PM is ‘entering the killing zone’, faces ‘assassination’ and should take ‘her own noose’ to a meeting. Few disagree with her more than I do, but language like this debases politics. Get a grip, Tories.
